Abstract
A luster pigment is described which is made up of a metal oxide film on a colored platelet-like support. The support is a pigment having a length of 3-150 .mu.m, a width of 3-150 .mu.m, and a thickness of 0.1-2 .mu.m. A process is described for the preparation of the pigment in which an organic platelet-like pigment is coated with a metal-oxide film by chemical vapor deposition. The preferred platelet-like organic pigment is .beta.-copper phthalocyanine.
